The specimen, a male, is a relatively large one, having a carapace 
15 mm. broad by 13 mm. long. It answers well to the figures given 
by Miers for a much smaller specimen, of which the carapace measured 
Simm. by 6mm. The emargination and sulcus of the front are well 
marked. The colour is “light red, yellow edging round carapace,” as 
given by Mr. H. W. Bell Marley. As preserved the carapace retains 
the red colouring, the chelipeds and other limbs showing white and 
red.

The genus has been noted by numerous authors: Adams & White, 
Dana, Heller, Paulson, Miers, Kirk, Filhol, Henderson, Alcock, Fulton 
& Grant, W. H. Baker, and McCulloch. For its characters see the 
following discussion of the single species for which it was originally 
founded. That it is apparently a link between the Oxyrrhyncha and 
the Catometopa has been pointed out by de Haan. Whether the 
typical species is as variable superficially in the latter tribe as //uenia 
proteus is in the former may be regarded as at present an open question.
